Enlarge the yard and raise some small fish in the water tank.

Keep goldfish in a big water tank. If you want to make money in the water, you should put it in front of the gate. If the gate is in the southwest corner of the yard, the vat should be placed in the southeast corner of the gate and the main entrance. If the gate is in the southeast corner of the yard, the vat is placed in the southwest corner of the road that the gate and the main entrance must pass through; If the gate is on the south side of the yard (rarely), the fish tank is placed on the connecting line.
